Hi Johnathan & Konstantin
Thanks for your explanation. It is very helpful to me.
I adjust the json file to fix this issue.
And I have one more question need help.
I try to enable the SEL, I add below setting
PACKAGECONFIG:append = " log-threshold log-pulse send-to-logger”
When event occurred, but SEL still empty.
event occurred log:
Jan 01 00:04:25 fws7830bmc adcsensor[283]: Sensor MB_P3V3 high threshold 3.531 assert: value 3.588 raw data 1794
Jan 01 00:06:08 fws7830bmc adcsensor[283]: Sensor MB_P3V3 high threshold 3.531 assert: value 3.54 raw data 1770
Ipmitoo sel log:
SEL Information
Version : 1.5 (v1.5, v2 compliant)
Entries : 0
Free Space : 65535 bytes or more
Percent Used : unknown
Last Add Time : Not Available
Last Del Time : Not Available
Overflow : false
Supported Cmds : 'Reserve’
Please give me some advice. Thanks
